The BSA of an AP covers the area used by the sales and marketing department. Thirty-five stations operate in this space. The users indicate that they…

The least expensive solution available for increasing throughput for these users without

implementing configuration options that are not recommended is to use a 40 MHz channel on the 5

GHz radio. This solution can double the channel bandwidth and increase the data rates for the 5 GHz

capable 802.11ac clients. Using a 40 MHz channel on the 5 GHz radio is also less likely to cause co-

channel interference or overlap with other channels than using a 40 MHz channel on the 2.4 GHz

radio, which has only three non-overlapping channels. Using a 160 MHz channel on the 5 GHz radio

may provide even higher throughput, but it may also consume too much of the available spectrum

and cause more interference with other devices or networks. Installing a second AP in the coverage

area may also improve the throughput, but it may require additional costs and

configuration. Reference: [CWNP Certified Wireless Network Administrator Official Study Guide:
